Why Investing in New Nuclear Plants Is Bad for the Climate: Commentary

New Coal Mines in the Australian Galilee Basin Are Not Economically Viable and Are Prone to Become Stranded Assets

To limit the effects of climate change, we must significantly curtail the trading and use of coal as an energy source. Although the rise of renewable energy sources has already led to a reduction in the demand for and use of coal, new export-oriented coal mine projects are still being approved, and they often receive strong political support. However, whether these projects are economically viable ...

Geographical Balancing of Wind Power Decreases Storage Needs in a 100% Renewable European Power Sector

To reduce greenhouse gas emissions, many countries plan to massively expand wind power and solar photovoltaic capacities. These variable renewable energy sources require additional flexibility in the power sector. Both geographical balancing enabled by interconnection and electricity storage can provide such flexibility. In a 100% renewable energy scenario of twelve central European countries, we investigate ...

Age and Gender Differences in Narcissism: A Comprehensive Study Across Eight Measures and over 250,000 Participants

Age and gender differences in narcissism have been studied often. However, considering the rich history of narcissism research accompanied by its diverging conceptualizations, little is known about age and gender differences across various narcissism measures.

Revisiting the Relatedness Hypothesis: The Impact of Merger Relatedness on Acquiring and Rival Firm Value  

Despite intuitive appeal, empirical evidence supporting the relatedness hypothesis has been scant, as it has not been established that related acquisitions generally outperform unrelated acquisitions. In considering the impact of merger relatedness on not only acquiring-firm value – as is standard in the relatedness literature – but also on non-merging rival firm value, we offer an alternative perspective ...

Class Rank and Long-Run Outcomes

This paper considers an unavoidable feature of the school environment, class rank. What are the long-run effects of a student's ordinal rank in elementary school? Using administrative data on all public-school students in Texas, we show that students with a higher third-grade academic rank, conditional on achievement and classroom fixed effects, have higher subsequent test scores, are more likely to ...

The Transition to Grandparenthood: No Consistent Evidence for Change in the Big Five Personality Traits and Life Satisfaction

Intergenerational relations have received close attention in the context of population aging and increased childcare provision by grandparents. However, few studies have investigated the psychological consequences of becoming a grandparent. In a preregistered test of grandparenthood as a developmental task in middle and older adulthood, we used representative panel data from the Netherlands (N = 563) ...

Trade Liberalization along the Firm Size Distribution: The Case of the EU-South Korea FTA

Leading theories suggest that amongst continuing exporters, lower variable trade costs should boost exports of smaller firms by the same or greater percentage rate than larger firms. However, investigating the impact of the deep EU-South Korea FTA with French customs data, we find robust evidence to the contrary. Applying a triple-difference framework, we report that the FTA increased sales in the ...
